HYDRAULIC PUMP.

Specification of Letters Patent.

Patented Nov. 16, 1909.

Application filed June 27, 1908. Serial No. 440,606.

v ful Improvements in Hydraulic. Pumps; and

1 do declare the following to bea full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form apart of this specification.

This inventionrelates to new and useful improvements in hydraulic pumpsof the rotary type.

The objects of the invention are to pro vide such type of pump combiningsimplicity of construction both with a view to efliciency and cost ofproduction, and to thus render the same available for a broad range ofuse, both domestic and otherwise.

The essential and desirable features of construction include the pumpcasing consisting of a hollow standard providing an inlet from below andan outlet from above, both inlet andoutlet being substantially invertical alinement, and an annulus located between said inlet and outletin which an impeller is placed, the fiuid entering the space between theannulus and the impeller and discharging from said space by lateralpassages around the ends of the annulus as will be hereinafter morefully described.

In the accompanying drawings, Figure 1, is an elevation of the pumpconnected'with an electric motor. Fig. 2, is an elevation with thedetachable side plate removed. Fig. 3, is a vertical longitudinalsection through the pump on the line a a of Fig. 2, with the detachableside plate in position. Fig. 4:, is a horizontal sectional view on theline b bof Fig. 2 with the detachable side plate in position. Fig. 5, isa sectional View through the head of the pump on the line 0 0 of Fig. 3.

In a detail description of the invention, similar reference charactersindicate corresponding parts.

The pump consists of two side plates 1 and 2, the former being integralwith a hollow standard 9 which provides an inlet for the fluid, and ascrew-threaded portion to receive a pipe 12 which provides for theoutlet from the pump, said inlet and outlet being in a substantiallyvertical alinement. The

side plate 2 is similar in construction to the side plate 1 but isdetachable from the pump. A ring 13 also forms a part of the samecasting, and as shown in Figs. 1 and 5, said ring forms opposite sidesof the pump casing and also the inner walls of the suction and outletchambers 18. The interior of said ring communicates with said chambersabove and below through inlet or suction ports 3 and 3 and outlet ports4. and 41 provided in the side plates 1 and 2 and communicating with theends of said ring. The impeller 14 lies eccentrically within said ringand the ports 3 and 4c are essentially on one side of a vertical planethrough the axis of the pump as shown in Fig. 5, and communicate withthe chamber or surrounding space 17. The shaft 7 of the impeller isextended through a hollow bearing 5, which is also a part of the singlecasting, which, as before stated, consistsof the hollow or pipe-likestandard 9, the side plate 1, the ring 13 and the screw-threadedaperture which receives the outlet pipe 12. The bearing is fitted with astutling box 6 and a drip pipe 8.

The impeller is provided with two blades 19 which are. expandedby-springs 20 to maintain them in contact witlrthe ring 13 as theimpeller is rotated, and the positions of the inlet and outlet ports aresuch that in the rotation of the impeller, one of the blades 19 hasforced the liquid before it through the outlet port, while the other ofsaid blades has opened the suction port below by a complete movementover it.

I11 Fig. 1, the pump is shown mounted on a base by means of the flangethereof with a suction pipe 11 communicating with the bottom thereof bybeing screwed intothe base or flange 10. The construction 1s sosimplified that it might be said to consist of practically a single pipewith a swell in the'body thereof to permit the fluid to enter said pipeand pass out of the pipe after passing around the impeller located inthe swell.

The pump as shown in Fig. 1 is driven from an electric motor 16, theshaft of which is coupled to the shaft of the pump by any common form ofcoupling. The outlet pipe 12 has connected to it a distributing i pipe12 which connects with a metallic pipe 1 12 leading to the storage tankor distributing system (not shown). The placing of the vibratory orflexible pipe 12 between the pump and the distributing system,materially lessens'the noise due to the forcingzof the waterthrough thepump.

Having described my invention, I claim: A pump of the type specified,consisting of a hollow standard constituting an inlet pipe and extendingon one side in a side plate and on two opposite sides in a swell orenlargement which extends in the form of a ring, an impeller within saidring, said swell or enlarged portion and the side plate 1 integrallyjoined to the hollow standard,

terminating at the top of the pump, in a screw-threaded nozzle orextension in ahne- 1 ment with the hollow standard, an outlet pipeconnected with said nozzle, the said f ring forming on the interior ofthe pump walls between the impeller and inlet and g outlet chamberscommunicating with the i hollow standard and the outlet pipe, and adetachable side plate opposite the integral side plate, said detachableand integral side plates providing ports leading from the in-. i letchamber below the impeller. to the interior of the ring, and fromthe'interior of I the ring above the impeller t0 the outlet chamber,substantially as specified.

In testimony whereof I affix my signature, in presence of two witnesses;

AUGUSTINE J. POCOCK. Witnesses CAROLYN M. THEOBALD, MATTHEW SmBnER.
